I know but can you just tell me if this is correct:
a = 1 b = 8 c= 5
x= -8 + square root 8^2 - (4x1x5)
- --------------
2
To determine if the given expression is correct, we need to follow the correct order of operations (also known as PEMDAS/BODMAS).
Let's break down the given expression step by step:
a = 1, b = 8, c = 5
Step 1: Evaluate the terms inside the square root (denoted as √):
8^2 = 8 * 8 = 64
Step 2: Calculate the value inside the parentheses:
4 * 1 * 5 = 20
Step 3: Subtract the result from Step 2 from the result of the square root in Step 1:
64 - 20 = 44
Step 4: Calculate the value inside the numerator (-8 + √44):
-8 + √44 = -8 + 6.63324958071 = -1.36675041929
Step 5: Divide the numerator by 2:
-1.36675041929 / 2 = -0.68337520965
So, the expression can be simplified as:
x = -0.68337520965
Therefore, the value of x is approximately -0.68337520965.
Please note that this explanation assumes that the expression you provided is as follows:
x = (-8 + √(8^2 - 4 * 1 * 5)) / 2
